6da70124a1 [MTD] CFI flash locking reorg for XIP
This reworks the XIP locking to make sure no lock primitive is ever
called from XIP disabled paths even if in theory they should not
cause any reschedule.  Relying on the current spinlock implementation
is rather fragile and not especially clean from an abstraction pov.
The recent RT work makes it even more obvious.

011b2a3627 [MTD] Fixup probing logic for single 16bit devices
The change to the generic probe to look for the
smallest width of chip first is causing some problems
on boards with a single 16bit device.

The problem seems to be the jedec_match() is truncating
the device-id read from the table to match against the
one read from the hardware, causing a match against the
partial id of some chips with 16bit IDs (such as the
SST39LF160)

This fixes things for my own board, but something may
need to be done if the same problem is exhibited for
chips with an 8bit ID

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
